SPECIFICATION forming part of Letters Patent No. 635,344, dated October 24, 18S 9.

Application iled December 30, 1898.

To @ZZ whom it' may concern:

Be it known that I, MICHAEL J. OWENS, a citizen of the United States, residing at Toledo, in the county of Lucas and State of Ohio, have invented certain new and useful Improvements in Machines for Blowing Glass, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention consists in a machine for blowing glass, and particularly in the construction and arrangement of the devices for eecting the blowing-that is, supplying the air-pressure and regulating the same-all as more fully hereinafter described, and particularly pointed out in the claims.

In the drawings, Figure l is an elevation of a machine of known type embodying my improvements. Fig. 2 is an enlarged section through one of the pumps and connections, showing the blowpipe supported in operative relation thereto. Y

A is the base of the machine, B is a standard, and O is a shaft supported in the base and standard and driven by any suitable means and carrying with it the mold-carriages D, each having a sectional mold E thereon, the arms F and G, which form supports for the blowpipes H, and the arms or head I.

The parts thus far described are of known construction and are normally constructed so that as the molds travel they are opened and closed and at one point in their travel are dippedinto a tank, where they are wetted and cooled.

In these machines as heretofore made the air-supply has been obtained from a source of air under pressure (such as a pump) at a distance and has been conducted by passages and pipes to the machine and there distributed to the various blowpipes and controlled by valves. This either requires a motor and pump on each machine with connecting-pipes or else a central pumping-station and pipes to the various machines. By my improvement each machine has its own airsupplying or air-compressing device and the air-supply pipes and ducts are avoided, the machine simplified, and valves omitted.

ings for the cylinder K, which is of a size to it over the end of the blowpipe.

To get the desired capacity, I may enlarge the end of the blowpipe-as, for instance, by the disk L, and to make a tight joint place the packing M around this disk.

O is a stem which is secured to the cylinder K and which passes through suitable guideways in the bracket a and carries on its top a block l), having an antifriction-roller c 6o bearing against stationary camway P.

Between the bracket and the block b is a spring Q, which sustains the weight of the cylinder and stem, the cam causing` it to move downward as the arm I moves and the 65 Vspring lifting it as soon as the shape of the cam permits. Thus as thel machine moves the cylinder is raised and lowered.

At the time the blowpipe is put in the machine the cylinder is up. As the machine 7o travels it is lowered, first to engage the blow pipe and thenl by its further movement to Vcompress the air for blowing the article, and

by its degree of movement it determines the amount of pressure. After the blowing the spring lifts the cylinder from the blow pipe, so that it may be detached and a new one inserted.

I show a guide-pin R for steadying the movement of the block l) and also a pinion 8o S on the stem O with a spine engagement, so that while permitting the sliding movement of the stem it will be rotated.

To prevent the collapsing of the blown ar ticle by the suction of the cylinder whenlifted, I provide a valve N, which opens to allow the cylinder to fill with air.

It will be seen in thisconstruction I have in'. effect two devices in the cylinder K, that cylinder, combined with the devices for caus- 9o ing it to couple with the blowpipe, forming, in effect, a coupler or air connection between the interior of the cylinder and the blowpipe, and after the coupling is effected the pumping function or action of the cylinder com 95 mences. Vhile Ihave shown these two devices andfunctions combined in a single thing,

I do not desire to be limited to the same, as I believe my invention is broad enough t'o cover a construction in which the coupling devices roo and thc aincompressingdevices are separate means, and the claims are intended to be drawn to cover such construction.

Vhat I claim as my invention isl. In a glass-blowing machine, a movable mold, a support for the blowpipe movable in unison with the mold, a blowpipe, an airsupply device and an air-compressing device, said blowpipe detachably supported in operative relation to the mold, the air-supply device, and the air-com pressing device movable with the hlowpipe.

2. In a glass-blowing machine, a traveling support for the hlowpipe and mold, theeblowpipe and aireompressing means moving with the traveling support and means for connecting and disconnecting the biowpipe with the aircompressing means.

In a glass-blowing machine, a mold, a support for ablowpipe and an air connection for the blowpipe adapted to be moved in unison, a blowpipe adapted to be supported in operative relation to the air connection and mold, and an air-compressing device carried with the air connection and' adapted to produce and supply to the blowpipe air at varying pressure.

l. In a glass-blowing machine, a support for the hlowpipe, a coupler having a closed top adapted to connect with the blowpipe, and means for moving it upon the blowpipe after the coupling to com press the air for blowing.

In testimony whereof I affix my signature in presence of two witnesses.

MICHAEL J. OWENS.
